The Contras were the various U.S.-backed and funded right-wing rebel groups that were active from 1979 to the early 1990s in opposition to the socialist Sandinista Junta of National Reconstruction Government in Nicaragua. Among the separate contra groups, the Nicaraguan Democratic Force (FDN) emerged as the largest by far. In 1987, virtually all contra organizations were united, at least nominally, into the Nicaraguan Resistance.

During their war against the Nicaraguan government, the Contras committed a large number of human rights violations and used terrorist tactics.[1][2][3][4][5] These actions were frequently carried out systematically as a part of the strategy of the Contras. Supporters of the Contras tried to downplay these violations, particularly the Reagan administration in the US, which engaged in a campaign of white propaganda to alter public opinion in favor of the contras,[6] while covertly encouraging the Contras to attack civilian targets.[7]

From an early stage, the rebels received financial and military support from the United States government, and their military significance decisively depended on it. After US support was banned by Congress, the Reagan administration covertly continued it. These illegal activities culminated in the Iran–Contra affair.

The term "contra" is short for la contrarrevolución, in English "the counter-revolution".

Shame on you. This is exactly the reason this kind of topic exists. Like, are you selfish or something? Each year, students become aggressive because of you, Bolsillos and guess what? They have a soul too. So how wouldn't they end up in a fit of rage for the consequences of your past actions? Grow up and get a grip.
